    Im not sure if I have the correct answer. HELP!!

    Solve by completing the square:

    x^2 + 8x + 3=o

    x^2 + 8x + 16 -13=0
    (x+4)^2-13=0
    (x+4)^2=13
    x1=sqrt13 - 4
    x2=-sqrt13 - 4


    or


    x^2 + 8x + (4)^2 = -3 + (4)^2
    (x+4)^2 = -3 + 16
    (x+ 4)^2 = 13
    x = + - (-4) sqr 13

    Are any of these correct?
